Puzzle over ‘Hubble constant’ could suggest many of our basic assumptions are wrong We may be fundamentally wrong about some of the deepest parts of the universe, according to a new study. For years, scientists have been puzzled over the “Hubble tension”. That refers to the difficulty over measuring how quickly the universe is expanding: different measurements show different speeds, and scientists have been unable to say why.

Summary: Researchers have identified a mechanism within the brain that underlies when we apply stored knowledge to novel decision-making situations.

We regularly find ourselves in new shops or restaurants, we land at airports we don’t know or start a new job. In such situations, the remarkable flexibility of human behavior becomes apparent. Even in new situations, we can often predict the consequences of our actions and thus make appropriate decisions.

In the not too distant future, trips to the мoon will Ƅe мanned and of long duration. In order for astronauts to surʋiʋe there for the duration of their мission, they мust first find a way to create oxygen, water, and fuel with the resources that exist there, since transport froм Earth is coмpletely unfeasiƄle.

Now, a teaм of Chinese astronoмers froм Nanjing Uniʋersity has just discoʋered how to achieʋe this and thus facilitate huмan exploration to create a perмanent Ƅase.

To take a picture, the best digital cameras on the market open their shutter for around around one four thousandths of a second.

To snapshot atomic activity, you’d need a shutter that clicks a lot faster.

Now scientists have come up with a way of achieving a shutter speed that’s a mere trillionth of a second, or 250 million times faster than those digital cameras. That makes it capable of capturing something very important in materials science: dynamic disorder.
